Application filed June 2, 1908. Serial No. 436,250.

To all whom it may concern:

Be it known that I, WILLIAM SnF'roN, of the city of Elizabeth, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Sash-Op crating Mechanism, of which the following is a full, clear, and exact specification, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to improvements in mechanism for operating sashes which are arranged in series along horizontal lines, for example, sashes such as are used in the construction of green-houses or hot-houses and other buildings.

The object of the invention is to provide a mechanism by which all the sashes of a horizontal series can be simultaneously opened or closed and by which there shall be assurance that they shall be all moved uniformly, and held rigidly in any position.

Figure l is a horizontal section of a series of sashes and showing in connection therewith an operating mechanism embodying my improvements. Fig. 2 is a vertical elevation showing one of the sashes and the means by which the operating devices can be actuated. Fig. 3 is a perspective view showing a part of one of the sashes, part of the operating rod, and a set of parts by which power is transmitted from the rod to the sash.

In the drawings, a wall structure is indicated at A, A A A having window openings at a, a a with frames having side parts 6, the top 6 and bottom at 6 In the window openings there are mounted sashes B, B B in a horizontal series of indefinite length. Each of these sashes is pivoted upon a horizontal casting so that it can swing outward and inward at the lower edge. To accomplish the moving by power of all of the sashes of the series simultaneously, I have devised the following parts: C indicates a sliding operating rod. It is arranged in horizontal lines below the lower edges of the sashes B, B etc. It and the parts attached thereto interposed between the rod and the sashes are all located below the glass in the sash and consequently there are no obstacles offered to the entrance of light rays or heat rays. The operating rod C is supported in frames or brackets D, the base-plates d of which are fastened to the wall or to the window framework at E below the sashes B, B etc. F indicates bell crank levers, each having a short arm f and a longer arm f At f each lever is pivoted to one of the frame brackets D. The longer arm f of the lever is at f pivoted to a link G which extends inward. and is pivotally connected to one of the shashes at g. This link G is at its ends so pivoted to the lever F and to the sash that it can freely play laterally back and forth and thus avoid clamping and binding. Each bell crank lever F is flexibly connected with the operating rod C by means of a link H which at one end is secured by a pivot h to ears k on the bell lever F; and at the other end it is secured by a pivot if to a bracket h This bracket can be adjustably fastened to the operating rod C by means of the set screw at if.

The rod C is caused to move longitudinally in one direction or the other by means of the nut I which engages with the thread ed section J of the rod. The nut I is formed with or secured to a bevel wheel K which engages with a bevel pinion L mounted on a shaft Z. The shaft 1 and the threaded part of the rod C are mounted in a bracket M which is secured to the wall structure of the building and has arms N, 0 formed integrally therewith. The shaft Z also has a hand-wheel P and by the latter rotation can be imparted to the pinion L, bevel wheel K and nut I; and when the latter is rotated it will cause the rod C to move longitudinally in one direction or the other through the bracket D. Preferably the operating rod C is angular in section and fitted in correspondingly angular eyes al in the bracket bars D. This insures that the operating rod shall be held against rotation and allowed to move only longitudinally. Vhen the rod O is forced in one direction it will, through the series of links 11, cause a swinging of the bell cranks F simultaneously in one direction, and the latter will in turn cause the sashes B, B B to swing uniformly either from the closed to the open position or vice versa.

I am'aware of the fact that rotary operating rods have been combined with vertically swinging sashes and that vertically arranged sliding rods have been combined with horizontally swinging sashes. But I believe myself to be the first to have so arranged the opening and closing mechanism of a long series of vertically swinging sashes that they can be tightly closed and opened freely simultaneously by a single operating rod and Which With its attachments is so arranged as to offer no obstruction to the free passage of the light rays and heat rays.

The sashes are in a horizontally disposed series of indefinite length and can all be actuated together, although each can be placed in a different position of adjustment in relation to the operating rod, so that notwithstanding Warping or twisting of any of the parts of the structure and notwithstanding lost motion at any point in the system, the sashes can all be tightly closed by a single movement of the operator.

What I claim as my invention is:

1. In combination. With a horizontally arranged series of movable sashes, a series of links respectively pivotally connected to each of said sashes, a series of stationary bracket arms, a series of levers pivoted to said brackets and to the said links, a single horizontally arranged reciprocating operating rod extending continuously along all the sashes of the said series, and a series of links connected to the operating rod and to the aforesaid levers, whereby all of the sashes of the entire series can be opened and closed by a single operating rod, substantially as set forth.

2. In combination With a horizontally arranged series of movable sashes, a series of links respectively pivotally connected to each of said sashes, a series of stationary bracket arms or frames D, a series of levers.

pivoted to the said brackets or frames and to the said hnks, a single horizontally arranged reciprocating operating rod below the horizontal planes of the sashes, a series:

of brackets adjustably mounted on said op erating rod and a series of links connecting the said adjustable brackets With the aforesaid levers, whereby all of the sashes can be moved simultaneously and uniformly, by a single operating rod and each can be independently adjusted relativeto said operating rod, substantially as set forth.
